If you're a hot sleeper who still wants memory foam, this is where the Fusion Pro makes its case. The copper-infused foam is designed to move body heat away faster than standard memory foam, and Sleepeezee says the copper adds antimicrobial properties too. Beneath that, a white fibre filling cushions spring movement and helps reduce allergens, and the 800 pocket springs adjust independently to your shape, which means less partner disturbance and support that follows your body rather than fighting it. Yes, 800 is a modest spring count compared with some premium hybrids, but the Which? Best Buy award and a from-price of £539 make it a sensible middle ground rather than a compromise.
Key Features & what's inside
- Copper Infused Memory Foam. The top layer uses memory foam infused with copper, which helps reduce heat build-up and moves body heat away more quickly, so you should feel noticeably cooler than on standard memory foam. Sleepeezee also credits the copper with antimicrobial properties.
- White Fibre Filling. A white fibre filling sits between the foam and the springs, cushioning spring movement so you feel a smoother surface rather than individual coils. It also helps reduce allergens, a small but welcome touch for sensitive sleepers.
- 800 Pocket Springs. The base is 800 traditional pocket springs that adjust independently, which means support that responds to your body shape rather than the whole bed moving as one. That independence also helps limit disturbance when a partner shifts position.

Who's it NOT for?
This isn't the mattress for you if you love a soft, enveloping feel: Medium-Firm has a supportive character, and lightweight side sleepers may find it slightly too firm at the shoulders and hips. Anyone wanting an all-foam feel with no spring response should also look elsewhere.
Sleepeezee Fusion Pro Mattress
Is the Sleepeezee Fusion Pro firm or soft?
Sleepeezee rates it as Medium-Firm. In practice that means a supportive feel with some surface cushioning from the copper-infused memory foam, rather than a soft, sink-in sensation. It suits back and combination sleepers well, although lighter side sleepers may find it a touch firm.
How deep is the Sleepeezee Fusion Pro mattress?
It's 25cm deep, which fits standard fitted sheets comfortably. That depth covers the copper-infused memory foam, a white fibre filling and the 800 pocket spring unit.
Does the Sleepeezee Fusion Pro sleep hot?
It's designed not to. The top layer is copper-infused memory foam, and copper helps reduce heat build-up and moves body heat away more quickly than standard memory foam. If you've found memory foam mattresses too warm before, this is one of the cooler-running options.
What guarantee does the Sleepeezee Fusion Pro come with?
Retailer listings for this mattress show a 10 Year Guarantee. Terms can vary by seller, so it's sensible to confirm the guarantee with whichever retailer you buy from.
How much does the Sleepeezee Fusion Pro cost?
Prices range from £539 to £944 depending on size, starting at £539 for the UK Single. It's also available in UK Double, UK King and UK Super King.
